Fixed in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/b6efe55f97c7).  Reporter can build from development sources or wait for the 3.6 release in December 2011 to see the fix.

This is a duplicate of bug #31468.  Multi-line text objects are possible with gnuplot, but have not been coded for the FLTK toolkit yet.

I used to insert '\n' in a string to get a items beneath each other with text() of gtext().

gnuplot does this, but the FLTK graphics_toolkit does not use the newlines.

---- below is what demonstrates the issue (when changing gnuplot to fltk).

octave:1> graphics_toolkit ('gnuplot')
octave:2> x=linspace(0,3,100) ; y=sin(x) ;plot(x,y,'r;sin(x);')
octave:3> s=sprintf('line1\nline2\nline3\n')
s = line1
line2
line3

octave:4> gtext(s)    %click on the plot somewhere.....
octave:5>

I think there should be 1 policy here, independent of the backend.
